If a Nezirah became Teme'ah and she separated Korbanos Tum'ah and then her husband annulled her Neder she brings the Chatas ha'Of but not the Olas ha'Of.
R. Yishmael holds that when a husband annuls the Neder of his wife the Neder is Batel retroactively.
R. Eliezer ha'Kapar holds that a Nazir is a sinner because he afflicts himself from drinking wine. (1)
According to R. Eliezer ha'Kapar someone who afflicts himself from all foods is certainly a sinner.
If a woman takes on Nezirus and her friend says v'Ani and the husband of the first woman annuls her Nezirus the second woman remains a Nezirah. (2)
If a woman takes on Nezirus and her friend says "I am like you" and the husband of the first woman annuls her Nezirus both women are Mutaros.
Rami Bar Chama asks if a person says he is prohibiting an object like the meat of a Shelamim whether his intention is for the meat in its previous forbidden state or for its present permitted state. (3)
It is a question to the Gemara if a woman says to a Nezirah Hareini b'Ikvayich, if the annulment of the first woman's Nezirus also annuls the Nezirus of the second woman.
If a woman takes on Nezirus and her husband says v'Ani he may not annul her Neder. (4)
If a person says that he shall be a Nazir and he asks his wife v'At and she says Amen, he may annul her Nezirus and his Nezirus remains. (5)
A BIT MORE
1. Even though the Pasuk only calls a Nazir Tamei a sinner that is because a Nazir Tamei accentuated his sin.
2. Because when a husband annuls a Neder he cuts it off and he does not uproot it.
3. The meat of a Shelamim is prohibited prior to the Zerikah and it becomes permitted after the Zerikah.
4. When he says v'Ani it is a confirmation of her Nezirus and he no longer may annul it.
5. When the wife says Amen she becomes a Nezirah but if she does not say Amen neither the wife nor the husband are Nezirim because the husband only wanted to be a Nazir if his wife would also be a Nezirah.
ASHAM OF A NAZIR
The Beraisa says that if a Nezirah became Teme'ah and she separated Korbanos Tum'ah and then her husband annulled her Neder she brings the Chatas ha'Of but not the Olas ha'Of. The Gemara says that according to the opinion that the husband cuts off the Nezirus she also brings the Olas ha'of. The Mefaresh says that she would not bring the Asham even according to the opinion that the husband cuts off the Nezirus because an Asham is only brought when the Nazir must recount his Nezirus and since the woman does not need to recount her Nezirus she does not have to bring the Asham.
If a woman is a Nezirah and she became Teme'ah during her Nezirus and then her husband annulled her Neder she brings her Korbanos Tum'ah. (Rambam Hilchos Nezirus 9:11)
Since we hold that the husband cuts off her Nezirus she must bring all of the Korbanos and not only the Chatas ha'Of. (Mishneh la'Melech)
